In physics, the conundrum known as the 'few-body problem,' how three or more interacting particles behave, has bedeviled scientists for centuries. Equations that describe the physics of few-body ...

Researchers at the Department of Energy’s Oak Ridge National Laboratory tested a quantum computing approach to an old challenge: solving classical fluid dynamics problems. For the test problem, the ...

University of Chicago physicists have succeeded in creating a vortex knot—a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...

“It is not easy to walk alone in the country without musing upon something,” Charles Dickens once observed. For Julian Barbour, those musings most often involve the nature of space and time. Barbour, ...

A college student in Switzerland says he’s solved a 100-year-old physics problem. The question is about an air bubble trapped in a very narrow tube of liquid, where the bubble appears to be “stuck,” ...

Physicists have developed a way to model quantum systems on everyday computers, making it easier to run complex simulations without relying on supercomputers or artificial intelligence (AI) tools. The ...
